Theory of operation

Base instrume

nt theory of operation

This section describes the basic operation of the major circuit blocks or modules

in the SPG8000 generator. The block diagram shows the modules and functional

blocks in th

e instrument. (See Figure 1.)

Information about the circuit blocks, including a detailed block diagram of the

Genlock/B

lack board, follows the SPG8000 block diagram.

Main board

The Main board consists of the following seven blocks.

Process

or core. The processor core consists of the C PU and all of its support

circuits such as ﬂash memory, DDR memory, clocks, buffers, reset circuit,

conﬁguration memory, and decoder PLD.

The CPU controls the front panel, LCD display, USB port, network interface,

GPI interface, and installed generator boards. The CPU also controls execution

of remote commands and downloading and uploading of signal ﬁles through

the Ethernet interface.

The ﬂash memory holds the ﬁrmware data and signal data used to generate

outputs from some modules. During Genlock, GPS or GLONASS referenced

operation, the CPU reads data from the input module, and controls the frequency

of t

he secondary clocks.

Ovenized oscillator. The ovenized o scillator provides the stable time base for

generating signals. This is a ﬁxed 20 MHz and is not adjustable.

Video / audio clocks. The synthesizer creates the video and audio clocks from the

ven output. The video clocks are a 54 MHz master clock signal and HD rate

clocks of 74.25 MHz and a 74.25/1.001 MHz. The audio clock is 12.288 MHz.

The CPU can control the ratio between the oven and these clocks. B y controlling

this ratio, the system can lock to external s ignals for Genlock, GPS or GLONASS

reference. The ratio is also adjusted to achieve calibration, with the resulting

value stored in ﬂash memory.

The 54 MHz and the 12.288 MHz are delivered to each generator card. For the

HD rate clocks, the CPU controls four m ultiplexers that independently allow

each generator card to get either the 74.25 MHz or 74.25/1.001 MHz clock. The

diagnostics monitor that each clock is correctly locked to the oven or master

54 MHz clock.

Frame pulse generator. The frame pulse generator uses the 54 MHz clock to

generate the three frame pulses at 2.997 Hz, 6.25 Hz, and 3.00 Hz that are used to

synchronize the signal formats generated by the installed options.

SPG8000 Master Sync / Clock Reference Generator Service Manual 1

Theory of operation

Theory of operation

DC/DC converte

rs. This block converts the +5 V supplied by the Power Combiner

board to –5 V, 3.3 V, 8 V, and 5 V analog for use by the circuit boards. Various

voltages needed only on the Main board, such as to drive the DDR and processor

core, are also provided.

The high current 5 V and 3.3 V voltages supplied to the slots are fused at the

connector to each generator board. All of the major voltages, including both sides

of each fuse, are monitored by the voltage diagnostic.

Network in

terface. This block controls the Ethernet interface.

The Ethernet port is located on the Breakout board at the instrument rear panel.

GPI interface. The GPI interface allows the CPU block to access the user inputs

and outputs through the GPI ports located on the instrument rear panel.

There are two GPI circuit blocks, GPI 1 and GPI 2. GPI 1 is located on the Main

board. GPI 2 is located on the Genlock/Black board. Both sets of GPI signals

route through the cable to the Breakout board. The Breakout board houses the

rear panel GPI, GPI/LTC, and Ethernet connections. The signals from GPI 1

are connected to pins 6,7,8 and 9 o f the 9-pin rear panel GPI connector. The

signa

lsfromGPI2areavailableonpins2,3,4and5ofthe9-pinrearpanelGPI

connector, and on pins 1,2,3 and 11 of the 15-pin rear panel G PI/LTC connector.

All of the GPI connections are available on the GPI port, but only the ones from

block GPI 2 are on the GPI/LTC port.

Power supply

The SPG8000 has a redundant power subsystem, which contains three major

components: the two power supply modules and the Power Combiner board.

Operation with one power supply m odule is also supported, but there is no

redundancy.

The power supply modules contain the line ﬁlter, the 100-240 VAC to 12 V supply,

a fan, and the power module board, which adapts the cables to a board-to-board

eader. The power module board also has LEDs to drive the light pipe that shows

power status on the rear panel of the power supply module.

The power module board has an EEPROM to log hours of operation. Since

the power module board tracks the use time on the other supply components,

replacing components within the supply module is not allowed.

The Power Combiner board takes in the 12 V from the one or two supplies, and

converts to 5 V for the rest of the instrument. If there are two good supplies, the

embedded microcontroller in the combiner chooses the preferred one. If either

supply has an issue, the m icrocontroller chooses the best one. 12 V storage

capacitors allow time f or the system to switch supplies without any disruption o f

the 5 V output. During the boot up of the combiner microcontroller, the combiner

functions in diode mode and uses the supply with the higher voltage, or a mix of

the two.

SPG8000 Master Sync / Clock Reference Generator Service Manual 3

Theory of operation

The Power Combi

ner board also has the fan controllers, so the speed of all three

fans can be set and se nsed by the instrument processor over the I2C interface.

The network interface signals pass through the combiner but only connect to

the two connectors.

An I2C interface is used to allow the processor to access the micro-controller

on the power combiner, the fan speed control, and the EEPROMS in the power

supply modules.

Optional m

odules theory of operation

The instrument has a standard Genlock/Black generator board, plus orderable

option boards. The options are: GPS Receiver board, AG board, BG board, and

SDI board

. This section describes the functions associated with those boards.

Option AG

This section describes the basic operation of the major circuit blocks in the

Option A

G A udio Generator.

Bus interface. This block provides the communication between the Option AG

circuitry and the instrument Main board.

Audio memory. This block contains 20/24 bits audio data for all of the serial

audio

outputs.

Audio data controller. The block is a part of the FPGA. It receives a udio data

from the Audio Memory and encodes thesedatatoserialaudiodatastreamthat

comply with the AES/EBU standard.

Cha

nnel buffers (1+2, 3+4, 5+6, 7+8, and silence). These blocks receive the digital

audio data from the FPGA and set the output amplitude to the speciﬁed level.
